Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover the safety profile (readOnly, idempotent, closed-world, non-destructive), yet the description still adds real behavioral context: results include summaries/outcomes, citations and uncertainty, missing actions or outcomes stay unknown, and past outcomes are not predictive. The one gap is that it never explains the ownership scoping as a hard filter versus a hint.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences with the core scope stated first and no filler. The final caution sentence earns its place as an epistemic caveat, though the middle sentence is a slightly dense run-on mixing three separate facts.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values needn't be spelled out, and the description usefully sets expectations about uncertainty and gaps. For a two-parameter retrieval tool, however, it leaves the semantics of `situation` and `limit` entirely undocumented, which is the main thing an agent needs before invoking it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description carries the full burden for two parameters, and it does not meet it. The required `situation` field's expected content (free-text description of the current case?) is only obliquely implied by "comparable," and `limit` (1-20) is never mentioned at all.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb-resource pair: find comparable recent runs or resolved feedback, with ownership scope ("owned by you"). It clarifies the ambiguous name word "cases" as runs/feedback, so an agent can distinguish it from siblings like search or ask_knowledge, though it never names an alternative directly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit when-to-use or when-not-to-use guidance, and no sibling is named as an alternative despite many plausible overlaps (search, ask_knowledge, query_work_dataset, get_feedback_status). Any selection signal must be inferred from the word "comparable" alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
